ReentryGuard.NOPRentryGuard (Logback-Parent 1.5.34 API)

java.lang.Object
- ch.qos.logback.core.util.ReentryGuard.NOPRentryGuard

All Implemented Interfaces:

ReentryGuard

Enclosing interface:

ReentryGuard
```
public static class ReentryGuard.NOPRentryGuard
extends Object
implements ReentryGuard
```
No-op implementation that never locks. Useful in contexts where re-entrancy protection is not required.
isLocked() always returns false. lock() and unlock() are no-ops.

Use this implementation when the caller explicitly wants to disable reentrancy protection (for example in tests or in environments where the cost of thread-local checks is undesirable and re-entrancy cannot occur).

public boolean isLocked()
```
    Description copied from interface: ReentryGuard
    
    Return true if the current thread holds the guard (i.e. is inside a guarded region).
    Implementations typically return false if the current thread has not previously called ReentryGuard.lock() or if the stored value is null.
    
    Specified by:
    
    isLocked in interface ReentryGuard
    
    Returns:
    
    true if the guard is locked for the current thread, false otherwise
  - lock
```
public void lock()
```
    Description copied from interface: ReentryGuard
    
    Mark the guard as locked for the current thread.
    Callers must ensure ReentryGuard.unlock() is invoked in a finally block to avoid leaving the guard permanently locked for the thread.
    
    Specified by:
    
    lock in interface ReentryGuard
  - unlock
```
public void unlock()
```
    Description copied from interface: ReentryGuard
    
    Release the guard for the current thread.
    After calling unlock() the ReentryGuard.isLocked() should return false for the current thread (unless lock() is called again).
    
    Specified by:
